Purpose
Drain diagnostic procedures including camera inspection protocols.
When to Use
- Slow drains, recurring clogs, sewer smell, or backup
Procedure
Initial Assessment
Which drains affected? All or just one? When did it start? History?
Single drain: localized clog (trap, branch line)
Multiple drains: main line issue
Sewer smell without backup: dry trap, damaged vent, or cracked lineCamera Inspection
Explain to customer what camera inspection involves and its value
Insert at nearest cleanout or access point
Record video and screenshot key findings
Identify: pipe material, condition, obstructions, root intrusion, bellies, offsets, cracks
Measure distance to problem using camera counter
Locate problem from above ground for excavation planningCommon Findings
Grease buildup: recommend jetting or enzyme treatment
Root intrusion: options from cutting roots to full replacement
Belly/sag: low spot collecting debris — usually requires excavation
Offset joint: severity determines approach
Solid object (caps, toys): be cautious with snake — camera inspect first when possiblePresenting Options
Show customer camera footage — most powerful sales tool for drain/sewer work
Present Good/Better/Best: clearing vs. jetting vs. lining vs. replacement
Free camera inspections offered as part of diagnostic (per team decision)
Optimizing drain blockage to main line diagnosis is a key revenue driverImportant Notes
- Save camera footage to ServiceTitan
- Camera is shared equipment — coordinate with dispatch
- If problem exceeds your scope (collapsed line), create estimate and schedule
- Always camera before AND after sewer clearing
